These uniquely beautiful  dichroic glass pendants have been carefully handcrafted by the skillful artists of Flame Work Designs in Victoria, BC Canada. Each and every one seems to have a life of its own! What makes this glass so sparkly and iridescent is a material called dichroic that is fused into the glass. Dichroic was invented in the mid 1970's by the aerospace industry. The glass is created in a vacuum chamber where a complex process vaporizes metal oxides and crystal quartz to form a film that adheres to the surface of the glass. *18 inch surgical steel chain necklace included.
